We describe 33 patients with recurrent COVID-19 and a positive PCR. Recurrence is associated with working as a healthcare professional, blood-group A, and low IgG response to infection.

Evidence from differential virus sequencing between the first and second episode supports de novo reinfection. Recurrent episodes tended to be more severe, with one fatal infection.
